IMPROVEMENT IN CARRIAGE-STEPS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we; CHARLES PARKsn and WILLIAM VOGLER, of Canterbury,in the county of Merrimack, and State of New Hampshire, have invented anew and improved Arrangement of Carriage-Steps; and we do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings making a. part of thisspecification, and to the letters of reference marked thereon.

This invention consists in communicating to the steps of a carriage sucha motion as insures their noninterference with the forward wheels wheneither of the latter approaches or comes in contact with the side of thecarriage during the operation of turning. a

To enable those skilled in the art to make and use our invention, wewill now proceed to describe its construction and operation. 7

A represents the bottom of a riding-buggy. a represents the stepsthereof, attached as usual at the sides between the forward and rearwheels in a position to facilitate entering the carriage. The steps areattached by pivots at p to the framework, and are provided withfan-shaped arms at, extending under the bottom of the carriage, thefunction of which is to distribute the strain brought upon the step bythe weight of the person entering the carriage over so large a spacethat no individual part of the portion enduring the strain shall be'injuriously affected thereby. To one side of each of the saidfan-shaped projections are jointed at ethe ends of connecting-rods b,the other ends of which are jointed to the outer ends of levers c,the'inner ends of which are united by rods 6 to eyesf, on the forwardaxle, at equal distances from the centre thereof.

Now, suppose the carriage to be turning to the left. During theoperation the left connecting-rod 6, receiving motion from the axle,forces the inner end of the left lever c backward. The consequentforward motion of the outer end of the left lever thrusts toward thefront the left connecting-rod]; and the left fanshaped arm d. As thelatter is pivoted at p, the step a, on the opposite of the pivot, ismoved toward the rear and right, and thus kept out of the way ofthewheel. At the same time the right connecting-rod b, also receivingmotion from the axle, draws the inner end of the right lever 0 forward.The consequent backward motion of the outer end of the right lever drawstoward the rear the right connecting-rod Z: and the right fanshaped armd. As the latter is also pivoted at p, the step a, on the opposite sideof the pivot, is moved toward the front and left, and thus broughtinto-a convenient position to receive the foot of the person gettinginto the carriage.

When the carriage is turning to the right the operations above describedare reversed,

It will thus be perceived that, in whatever direction the carriage maybe turned, one of the steps is gotten out-'of the way to preventinconvenience, and the other brought in the way for the sake ofconvenience. Two steps or more can be used upon each side, if desired.

What we claim, and desire to secure by Letters Patent, is-

1. A vibrating carriage-step, operated by mechanism connected with theforward axle, substantially-as described.

2. The vibrating step a, in combination with the fan-shaped arm (I,lovers 6 b, and cross-bar a, substantially as described.

3. The step (1, provided with fan-shaped arm d, substantially asdescribed.
